Select a modular blade for face grooving, so that the cutting diameter at the first pass is within the range of DAXN minimum and DAXX maximum that are described in the table of dimensions.
Select the shortest possible blade suitable for the application.
•Select the largest size blade within the maximum cutting diameter of the workpiece.
•Machine from the outer diameter towards the centre.
•Increased machining stability and rigidity is possible if a modular blade with the largest possible back metal is used.
At first machine the maximum cutting diameter, there is no restriction in the cutting diameter on the remaining process.
To ensure sufficient clamping rigidity, select a modular holder with the largest possible shank size.
•Set the cutting edge height to ±.004" parallel to the central axis.
•Cutting edge center height check should be done by traverse machining towards the center with a very small depth of cut and ensure that an even surface and no material remains at the center point afterwards.
If interference occurs even when the correct blade is used, the cutting edge height could be incorrect.
When interference occurs on the inner side of the blade, the cutting edge height is set too high.
When interference occurs on the outer side of the blade, the cutting edge height is set too low.
